To all whom t may concern.'

Be it known that I, Lewis H. SELDEN, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful 'Improvements in Fireproof Windows, of which the following is a specification.

The object of my invention is toprovide a lreproof window having a sash frame that is capable of adjustment with respect to the window sash, and a particular object of the invention is to provide lan adjusting means easily accessible and operable to obtain the desired adjustment when the frame and the sash have been assembled.

Further objects of the invention will appear from the following detailed 'descripf tion.

The invention consists generally in various constructions and combinations, all as hereinafter described and vparticularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a perspective viewi of a portion of a window frame and sash embodying my invention, F ig. 2 is a horizontal, sectional view illustrat-ing the adjustable portion of the frame and the means for operating it, Figs. 3 and 4 are detail sectional views of the adjustin mechanism', Fig. 5 is a detail view of the locking plate by means olf Kwhich the independent outward movement of the adjusting screw is prevented. j

In the drawing, 2l represents the'window or sash frame composed of sheet metal having the sash weight pockets 3 and 4 separated by a division plate 5. This frame as indicated, is formed of one piece of metal and on each side of the sash shoulders Y6 are formed in the metal to bear on the surface of the wall. vThe metal forming the shoul` der 6 is bent inwardly to form fiat faces 7 in planesvat right angles substantially to the v plane of the window sash and these faces terminate in inwardly turned flanges 8 having outwardly turned ends 9.

10 represents a plate sometimes designated as a pulley stile having outwardly turned vertical edges 11 which la by th'e ends 9 on each side of the sash, as indicatedV in- Fig. 1, but without being attached to .these ends. A parting bead 12 is formed on .the pulley stile lnear the middle thereof and rates thesash 13-from the one on' the ot er'side of the stop.- The lpulley stilel is 'movable for the l'n'the window, ment,'and is purpose of" yfitting the sash o r for subsequent adjustprovided with strengthening 4bars 14. anda screw bolt 15 whichfpasses through the hollow parting bead 12 andintO a threaded socket in a bar 16` that is secured at lts ends to the shoulders 6, and extends transversely of theiframe between' the pulley stile and the sash weight pockets, as shown clearly in 2. 4'Ihebar'lll hasa hole '1 7 therein in which a screw bolt 15 is movable and by rotating this .screw the pulleystile may be moved back land forth toward and from the window'sash, until the desired lafd-r justment is obtained. `The bead 12 li'as a hole 18 therein through which access may be had to the screw bolt with a screw driver.

Patented Aug. 26,1913.

It is evident, however, that if the screwlbolt be rotated wit-hout some means Aforv preventlng its longitudinal movementfswith respect to the pulley stile, that'no adjustment of the stile couldzbebt'ained. I'therefore provide a locl'ingplat'e 1,9 movable in f ides in .tI e bead 1 2 and having hles accessibe through a slot21inlsaid bead'and a larger hole 22`that is adaptedto partially cover the head of the screw the bead 12 auditv e pulley stile. Thls lock- Iing plate :is capable ofuvertical movement and may be pushed up and down readily by means of a tool inserted through vthe xslot 21 into one of the holes 20. f Lugs 2 34 areyprovided on ysaid i with the bars 14 and limit the downward movement of the plate. 'A stop 14; limits the vertical movement of Athe 'plate 1'9. When this plate is pushed down to its operative` position, as shown in Fig. 3, it will'cover t e outer portion or rim of the head of the screw bolt, and while the slot in the bolt will be accessible through the hole 22 for a 'screw driver, the plate cannot move lengthwise l bolt 15 and prevent it from moving longitudinally with res ect to platenin position to' contact with respect to the stile, the rotation of the bolt ycausing it to move in and out in the bar 16 and adjusting the stile toward or Ifrom said bar until the stile has been properlyV set for the width of the window sash.

' The adjustment of the stile is very simple, being easily accessible from the inside or outslde of the window and may be usedl on one or both sides of the window. Its action is positive and when .the adjustment is complete -and the plate 19 moved to its locking position, it will be impossible for the stile to move on the bolt or change its position with respect thereto without revolution of the screw.

The Pulley stile is preferably a little wider than the combined thickness offboth sash, as plainly shown in Fig. 2. This allows the accurate fitting of the sash in the Window, even though there may be a variation in width between the top and bottom of the frame due to various causes,v or there may be a slight difference in the width of the sash themselves. By providing a stile the ull thickness of both sash I can readily obtain the necessary adjustment and t the sash to slide smoothly in the frame after the frame has been set up in the building wall,

and by locating the adjusting means in the parting bead between the sash, I can have easy access to the adjusting -means from either side of the'window. This I regard as an important feature o my invention.

The bar 16, in addition to its function of supporting the screw 15, strengthens, braces and holds in place the metallic frame of the window and aids materially in its power of resistance to heat. I havev shown but one of these bars and screws, but any suitable number .of them may be employed, aocording to the height of the window.

I claim as my invention l. A 'fire-proof window frame including a jamb, a pulley stile, a parting bead thereon, an upper and lower sash, said stile being of greater width than the combined thickness of both sash, a screw fitting within a socket in said parting bead between said upper and lower sash and passing through said stile and into a threaded socket provided in therear of said stile, said screw being accessible from either side of the Window and its lengthwise movement causing said stile to be adjusted toward or from said sash to adapt the window to sash of different width.
